MDZA series magnetic drive pumps use effective permanent magnets with reduced unwanted eddy currents to maximize the working efficiency. Flow passage are statically sealed inside, preventing the liquid from leaking and being polluted. Axial thrust balancing allows the pumps to operate stably and quietly, while providing outstanding smoothness and reliability during rotor operation. The pumps also use safety devices to reduce idling and overloading. The pumps are used in a wide range of industries and are suitable for pumping inflammable, potentially toxic, volatile, highly corrosive, and easily condensed liquids.
